Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
A silicon transistor is a transistor made of silicon.
Germenium and silicon are the examples of Semiconductors.
high permeability ,low hysterisis,increased resistivity
produces magnetic properties,such as small hysteresis area and permeability Hysteresis loss depends upon the material of the core

permeabiity
Silt has neither high or low permeability. It has moderate permeability. :) !
A stable, nonmagnetic austenitic alloy steel having extremely low magnetic permeability especially in the unannealed condition, and consisting essentially of, in percent by weight, carbon 0.35 to 0.45, manganese 14 to 16.5, phosphorus 0.05 max., sulfur 0.07 to 0.12, silicon 0.55 to 1.15, nickel 3.5 to 5.5, nitrogen 0.12 max., chromium, 0.50 max. and the balance iron and incidental impurities.
Silicon steel, an alloy of iron with a small percentage of silicon (typically around 3%), exhibits excellent magnetic properties, making it ideal for electrical applications such as transformers and electric motors. The addition of silicon enhances the material's electrical resistivity, reducing eddy current losses and improving efficiency. It also increases the magnetic permeability and saturation induction, allowing for better magnetic performance. Overall, silicon steel's magnetic characteristics are crucial for optimizing energy conversion and minimizing losses in electrical devices.

permeability
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
permeability
1. The permeability results might be localized due to excavation. 2. Lateral permeability not considered which may lead to erroneous estimate of field permeability.
